1)编写DFT子函数（计算并画出幅频特性），以后可调用。 2）N=32，M=32，128，256时，分析频率分辨率、频谱的光滑程度。 3）N=64，256，512时，分析频率分辨率和频谱的光滑程度。 (1) the preparation of DFT Functions (calculated and drawn amplitude-frequency characteristics), the future can be called. 2) N = 32, M = 32,128,256, the analysis of the frequency resolution, the degree of smooth spectrum. 3) N = 64,256,512, the analysis of the frequency spectrum resolution and the degree of smoothness.)

说明：  创建一个复数类，定义属性：实部、虚部。定义方法：复数加法、复数减法、复数乘法、求实部，求虚部，将复数输出，判断两个复数相等。通过一个类举例验证这些方法(Create a complex number class, custom attributes: the real part, imaginary part. Definition method: complex addition, complex subtraction, multiplication, complex, realistic Department, seeking the imaginary part, the complex output, determine the two complex numbers are equal. Verified through a class example of these methods)

说明：  昨天刚刚写好的dsb-sc信号生成与解调程序，用离散（dsp）的方法生成DSB信号，载波频率为150khz,音频是500hz和2000hz的混合音，加入SNR=1DB的噪声，用正交解调实现解调，画出解调前后的频谱图，欢迎共同学习，进步。(yesterday just finished the dsb- sc signal generation and demodulation process, discrete (dsp), the signal generated DSB, the carrier frequency of 150kHz, audio is 500Hz and 2000hz mixed audition to join SNR = 1DB of noise, with quadrature demodulator to achieve demodulation, paint around the demodulation spectrum welcome to learn together and progress.)

哈工大的数学实验的大量的matlab仿真例程，包括莫比乌斯曲面簇的数学模型研究等内容，以及matlab界面设计等(HIT mathematical experiment matlab simulation routines, including Mobius surface the mathematical model of research clusters, as well as Matlab interface design)
